24. A, C

In planning a mural, the position of the observer should be considered: We want people to take in our mural—all of it—from a moving position, since they ’ll be observing it as they walk through the lobby to the elevators. The architecture of the room should also be considered: A mural is an integral part of the building. If it’s painted in an existing building, like ours will be, it should be planned to fit into the architectural design…. (2.2)

Yes: Moisture seeps through the wall and dissolves salts in the wall material: When water leaks through a wall, it may dissolve the salts that are in the building materials,

No: The plaster dries more quickly than the paint: Not mentioned in the discussion.

No: An air space between the interior and exterior walls insulates the mural: …an air space of one-half to one inch between the outer and inner walls. That’s enough to protect our mural from moisture….

Yes: Dried salt deposits form a white film on the mural: When the moisture dries, the salts are deposited in the form of white, moldy-looking film on the surface of the plaster. (2.6)

27. A

The student says We could create an air space between the outer wall of the building and the plaster; The air space would have an insulating effect. What I mean is, it would slow down any temperature changes on the plaster. (2.2)

28. C

The instructor’s purpose is to explain how to create an insulating air space between the outer and inner walls. The instructor describes how to build another wall on top of strips of wood attached to the inside surface of the wall. The mural will be painted on this new wall. (2.3)

The professor’s purpose is to give an example of an environmental cue. The professor explains that some seeds require a specific environmental cue for germination. Then he gives the example of a heavy rainfall, an environmental cue that causes desert plants to germinate. (2.3)

32. B, D

Water is an environmental factor that seeds require for germination: Water is a basic requirement, and no seed will germinate unless it absorbs water. Another factor is the proper temperature: Germination also requires a certain combination of temperature and light…; Each plant species has an ideal temperature at which the largest number of seeds will germinate. (2.2)

33. C

The professor says For a seed to sprout and grow, it needs a great deal of energy. Seeds get this energy by converting the energy of their stored fuel molecules…. (2.2)

34. C-B-D-A

The professor says (1) When the embryo takes in water, it often swells to several times its original size; (2) The first organ to emerge from the germinating seed is the embryonic root.
